Factor Polynomials with Complex Numbers: Practice
Показать описание
This video continues the topic of factoring polynomials with complex numbers by looking at another example problem from the Khan Academy exercise linked below.
The problem analyzed works through factoring a sixth degree polynomial into linear factors and we need to determine the mistake. Problems where a mistake needs to be found are useful since they help students find mistakes in their own work.
Factoring a difference of squares, factoring a sum of squares, factoring the greatest common factor, and factoring fourth degree polynomials with substitution are all techniques needed to understand the approach to this problem.
